Do you have multiple bank cards or do you you have just one? Do you have a savings and checkings account or just one of the two? Personally, I have a bank card with just a checking account on it, and a Paypal debit card as well. I usually just give myself a set amount of money to spend during the week and it's been working pretty well. I haven't had the need to ever get a savings account.
I don't have multiple bank accounts as I'm currently broke I do prefer to have at least three bank accounts or three cards, when I'm in employment or have a lot of money coming in. A current account, a savings account and one of those pre-loaded cash cards. I used to use credits cards, but after paying them off and cutting them up, I want to keep moving forward and managing my money a bit more wisely
